  1. ExtremaRatio - Ferrum T knife - Black Warfare - knife

    Ferrum T is a folding knife with a clear tactical connotation equipped with a spear point blade with lightening slot. It has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system.

    Equipped with a flipper assisted opening system, the blade rotates on ball bearings which allow a smooth and uncertain movement of the blade. This mechanism allows the user to open the blade quickly and easily, even with just one hand. The locking system adopted is the well-tested liner lock. The reversible clip is positioned on the back.

    Ferrum T is available in 2 versions: the first, FERRUM T Black Warfare, equipped with a black handle and Geotech Camo blade, the innovative and original Extrema Ratio camouflage pattern, created by laser engraving. The second, FERRUM T TACTICAL MUD, with anodized handle in the new gray-green color and blade with MIL-C-13924 bluing.

    The reversible clip is positioned on the back.

  3. ExtremaRatio - Ferrum Rescue multi tool - Black - knife

    Ferrum Rescue is a tool designed for rescue operations, developed in collaboration with my friend Andrea Micheli, military and law enforcement expert, journalist and shooting instructor. Made with a very compact handle, this rescue tool is equipped with 3 blades, each of which has a specific function:

    The first and main blade has a thickness of 3 millimeters and is designed to be used for more demanding purposes and to protect the cutting edge of the other two from premature wear. The teeth allow it to cut larger ropes or textile materials, the remaining smooth part has the classic function of a knife. The second blade is a scalpel, which can be used for extremely precise cuts and for emergency first aid interventions. The third blade, on the back of the first, is the smallest of the 3, it has the function of cutting lines, capable of cutting paracord and aramid material.

    The interaction of the main blade with the scalpel allows the operator to make a quick emergency cut to free any injured person from his or her clothing.

    The line cutter blade and the scalpel are both interchangeable.

    Ferrum Rescue has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system. On the back there is also a hard metal glass breaker.

    Equipped with a flipper assisted opening system, the blade rotates on ball bearings which allow a smooth and uncertain movement of the blade. This mechanism allows the operator to open the blade quickly and easily, even with just one hand. The locking system adopted is the well-tested liner lock. The reversible clip is positioned on the back.

  7. ExtremaRatio - BF2CD Knife Stone Washed - Classic Drop - knife

    The BF2 is a "full size" lockable particularly suitable for professional use by military and police operators in the field. The handle is firm and comfortable; the clip, reversible and enveloping, becomes a useful and comfortable support for the thumb in "reverse grip". The grip is full with the characteristic lowered surfaces to engage the opening "pins" without protruding from the profile of the closed knife. The blade, available in a drop or a lot version, has a flat edge and, as in the BF1, a particularly thick and resistant tip. The blade locking mechanism is the tested LINER-LOCK, assisted by a safety mechanism to be operated manually protected by a casing.

    Blade: N690Co 58HRC stainless steel

  8. ExtremaRatio - BF2CT Knife Stone Washed - Classic Tanto - knife

    Il BF2 è un chiudibile “full size” particolarmente indicato per l’impiego professionale da parte di operatori militari e di polizia sul campo. L’impugnatura è salda e confortevole; la clip, reversibile ed avvolgente, diventa un utile e comodo appoggio per il pollice in “reverse grip”. La guancetta è piena con i caratteristici piani ribassati per impegnare i “pin” d’apertura senza che sporgano dal profilo del coltello chiuso. La lama, disponibile in versione drop o tanto, ha l’arrotatura piatta e, come nel BF1, la punta particolarmente spessa e resistente. Il meccanismo di blocco della lama è il collaudato LINER-LOCK, coadiuvato da un meccanismo di sicura da azionare manualmente protetto da un carter.

  9. ExtremaRatio - Resolza 10 - Black - pattada knife

    RESOLZA, a term of ancient origin, is today one of the most famous traditional knives of our country. The name suggests the razor by chance.

    It was born in Sardinia centuries ago and has accompanied its inhabitants until today in the daily work of a peasant and pastoral life, following them even when its men were called to war. The chronicles of the Sassari Brigade during the First World War cite this knife among its soldiers' equipment.

    We wanted to make a tribute by revisiting it according to our canons, without wanting to hurt any of the prestigious Sardinian artisans who still today pass on the tradition and wisdom of their ancestors. The dimensions and proportions are the original ones of a 10 cm blade, but the materials and technologies are those of our production. The handle revised in our style, the blade most faithful to tradition. In addition to the original, it has the blade lock open.

  27. ExtremaRatio - BF2 V Stone Washed Knife - Sailing Knife

    This knife was designed and perfected in every detail for its primary use in the marine environment. The blade has a flat rounding that allows symmetrical cutting work with wider support. The tip, on the other hand, which is thick and durable thanks to the tanto version, allows greater penetration and a sharper, more precise cut. The stone washed finish process facilitates locating in the marine environment.

    The structure of the handle, made of anodized anticorodal aluminum, features a design with milling in concentric circles and lightening and anti-slip perforations so as to facilitate rinsing from saltiness. A small slot is cut into the middle of the cheek piece to allow for tightening or releasing smaller shackles. BF2 V is equipped with reversible clip; adjusting screw retainer for closing and opening the blade; 70-mm. knot shock ankle with fastening mechanism; and correctable. The presentation of the BF2 V took place on the Amerigo Vespucci School Ship.

  36. ExtremaRatio - Ferrum Rescue multi tool - Red - knife

    Ferrum Rescue is a tool designed for rescue operations, developed in collaboration with my friend Andrea Micheli, military and law enforcement expert, journalist and shooting instructor. Made with a very compact handle, this rescue tool is equipped with 3 blades, each of which has a specific function:

    The first and main blade has a thickness of 3 millimeters and is designed to be used for more demanding purposes and to protect the cutting edge of the other two from premature wear. The teeth allow it to cut larger ropes or textile materials, the remaining smooth part has the classic function of a knife. The second blade is a scalpel, which can be used for extremely precise cuts and for emergency first aid interventions. The third blade, on the back of the first, is the smallest of the 3, it has the function of cutting lines, capable of cutting paracord and aramid material.

    The interaction of the main blade with the scalpel allows the operator to make a quick emergency cut to free any injured person from his or her clothing.

    The line cutter blade and the scalpel are both interchangeable.

    Ferrum Rescue has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system. On the back there is also a hard metal glass breaker.

    Equipped with a flipper assisted opening system, the blade rotates on ball bearings which allow a smooth and uncertain movement of the blade. This mechanism allows the operator to open the blade quickly and easily, even with just one hand. The locking system adopted is the well-tested liner lock. The reversible clip is positioned on the back.

    The reversible clip is positioned on the back.

  40. ExtremaRatio - N.K.1 Neck Knife - SanMai V-TOKU2 - Limited Edition - NK1 - Knife

    Japanese steel merges with Italian excellence

    For this 2021 collaboration, exclusive to Coltelleria Collini, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically we have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

     

    Intended Use: Neck Knife / Collector's Knife

    Type of production: Industrial
    Country of Production: Italy
    Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
    Blade finish: Satin finish
    Blade length: 40mm.
    Blade thickness: 3mm.
    Total length: 129mm.
    Weight: 55g.
    Sheath: Kydex, for neck.
    Packaging: Cardboard box with Extrema Ratio logos.
    Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

     

     

    As in the ancient swords of the Japanese Samurai.

    The rolled steel - imported in Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

    Characteristics of San Mai steel: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:

    - Longer cutting edge life
    thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.

    - Greater resilience
    Built on the principle of Japanese swords, the multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the lateral coating (Stainless Steel).

    - Improved corrosion resistance
    The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

    - Easy machining even after heat treatment
    Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

    - Improved aesthetic performance
    Knives made of multi-state steel or damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.
